Description

1.

  The present invention relates to an aerodynamic deflector

  for a motor vehicle. In particular, the preface

  This invention relates to an aerodynamic deflector which can be mounted on a vehicle, conveniently of the type comprising a cabin and a rear body, the front wall of the body

  having dimensions larger than those of the cabin.

  Many types of aerodynamic deflectors are known

  intended to be fitted to motor vehicles of the above type. These include, for example, baffles to be mounted on the roof of the cabin to melt

  the line of the respective roofs of the cabin and the body.

  Others are fashioned appropriately so as to

  cover the edge of the front wall of the body, on the con-

  gu to the cabin, and therefore round the profile of the

  adjacent to the front edge of the crate.

  Known deflectors of the type discussed above

  have a specific structure and are generally manufactured

  in various sizes so as to allow their assembly

  on different models of motor vehicles. This is

  of course, a considerable increase in manufacturing costs, for the construction of the different types of

  deflectors, and in addition require separate stocks of

  first and second equipment.

  The object of the present invention is an aerodynamic deflector designed to overcome the above disadvantages.

  which are typical of known types of deflectors.

  According to the present invention, deflection is

  aerodynamic engine for a motor vehicle of the type comprising

  both a cab and a rear box, the front wall of the box having dimensions greater than those of the cabin and extending beyond its upper side and its opposite sides, characterized in that it comprises a number semi-tubular, rectilinear and elbow-shaped elements, which can be connected to each other and mounted on the edge of the front wall, in order to round the profile of the area

contiguous to the edge.

  The present invention will be well understood during the

  following description made in conjunction with the drawings

  joints in which: Figure 1 shows a motor vehicle equipped

  a deflector according to the teachings of the present invention.

  tion; Figure 2 is a sectional, large-scale view taken along the line II-II of Figure 1; FIG. 3 is an exploded view, on a large scale, of the deflector of FIG. 1, a certain number of parts

being eliminated.

  The reference 1 represents in FIG. 1 a motor vehicle, in particular a truck consisting of a cab 2

  and a box 3 overflowing on the top and the side parts

  2. The reference numeral 5 represents an aerodynamic baffle according to the present invention, which consists of a number of semi-tubular, rectilinear and elbow-shaped elements 7 connected to one another and mounted on the edge of the front wall 8 of the body 3, so as to define a frame having a rounded profile and covering 3. the upper and lateral parts of the body 3. As

  represented in FIG. 1, the elements 6 and 7 constituting the

  flector 5 combine to define a continuous surface

  aerodynamic deflector which acts sensitively

  in a single, U-shaped, semi-tubular deflector

  on the edge of the front wall 8 of the body 3.

  In connection more particularly with Figures 2

  and 3, each element 6, 7 constituting the deflector 5 presents

  a section in substantially semicircular section. From a

  In more detail, from the longitudinal edge of each element 6 and 7, a tab 11 extends perpendicularly, which in actual use rests on the surface of the wall 8 of the box 3 and is attached thereto, for example, by some

number of screws.

  On the opposite side to the one presenting the leg 11, each

  that element 6 and 7 has another leg 12 (Figure 2) extending in a plane perpendicular to that in which

  is located the leg 11, so as to rest, using

  on the edge of the side wall 13 of the body 3,

  at the point of connection between the wall 13 and the wall 8.

  Finally, each element 6 and 7 presents, on one end,

  mity, a semicircular end portion 14, whose diameter

  outer surface is substantially matched to the diameter

  of the inner surface of elements 6 and 7. In

  tion, this allows the contiguous elements 6 or 7 to be subjugated together by partial overlapping of the

elements.

  Each element 6, 7 of the deflector 5 can be conveniently

  molded plastic material, or fiberglass, to obtain an extremely high resistance to mechanical stresses.

  The advantages of the deflector of the presentation

  The invention will become apparent from the foregoing description. In

  First and most importantly, it is possible to easily mount the deflector 5 on the wall 8 of the box 3, since it is given that a single element is mounted each time. In addition, the possibility of a serial connection, as necessary, of a number of elements 6 and their cutting to the desired length, obviously allows the formation of different deflectors for mounting on motor vehicles having crates

  different, although only two basic elements, that is,

  re rectilinear elements 6 and elbow elements 7,

be employed.

  Thus, the manufacture of the basic elements of deflec-

  5 is greatly simplified, as is also the storage, which requires much less space than that generally required for deflectors ready to be

  mounted on different vehicles.

  Those skilled in the art will appreciate that changes can

  can be made to the deflector 5 just described and illustrated

  without departing from the scope of the present invention.

  For example, the motor vehicle on which the deflector 5 is mounted may be a truck, as shown in FIG. 1, or a trailer comprising a tractor.

and a semitrailer, etc.

  The present invention is not limited to the examples

  described above, it is, on the contrary,

  re susceptible to modifications and variants that will appear

to the man of the art.
